hi,smileguitar said:Sorry, what do you mean a known working LCD driver programme? I think I never tried it before. Really sorry, this is the first time I touch LCD and not really know about the well known LCD driver programme. erm... How it is try...
Thanks!!
Its the one I posted a few days ago,, IIRC.... 'lcd2line'
To determine the cause of a problem, sometimes you have to use a known 'good' program or component.
For example: say you had a spare LCD on the shelf, you would try it in the place of the suspect one. If it worked with the new one that would most likely mean the first one is faulty.
If it still didnt work with a new LCD that would mean the problem is most likely something else other than the LCD.
The same applies to a program,, the program i posted works with a HD44870 LCD controller and the same type of PIC that you are using.
If my program drives the LCD OK, this means the fault is most likely your program,,, if the LCD dosnt work with my program then either the LCD is faulty or the LCD wiring is faulty.
Its necessary when fault finding to go thru a process of elimination, using devices or programs of known quality...
Do You follow this???
Its this one.
